in leaves in gas form
roots in liquid |

Term
|
Definition
down from leaves to rest of plant
sometimes stored in stem or roots- so moves up also |
|
|
Term
|
Definition
| fungus helps plant absorb water and nutrients |
|
|
Term
|
Definition
cell pumps ions in and out against gradient
requires ATP
used to help bring nitrate into cell
used to move sugar between cells
Hydrogen |

| barrier for water to the xylem |

Definition
root pressure
adhesion/cohesion
atmosphere/transpiration |

|
Term
|
Definition
actively transporting ions
lowers WP- water will then follow
gravity prevents water being pushed up all the way |
|

Term
|
Definition
helps mvt
water sticks to container and to other like cells |
|
|
Term
|
Definition
water evaporates out of leaf=> lower WP (tension)
water pulled up to leaves
stomata crucial
guard cells |
|
|
Term
|
Definition
can sense water level and control how open stomata are
pump K ions into cells to encourage water to move into G cells (low WP)- when lots of water available |
|
|
Term
|
Definition
solutes move into sieve tube, lowers WP
water from other cells move into tube
forces sugars to move through tube |
|
|
Term
| Source to Sink translocation |
|
Definition
source: where sugar is made
sink: where sugar is needed |
